3. Magnetic Shape Memory Alloy (MSMA) –Ni 2 MnGa –Magnetization vector rotation –Actuating vs. power harvesting Variant Reorientation Model

4. Problem Definition Goal –To design a piece of equipment that will facilitate the already established testing procedure and enable forces in the lateral direction. Design Objectives –Cost-efficient –Precise –Reliable

5. Problem Identification Dr. Ciocanel Conducts research on Smart Materials Wants to expand his testing process to include compressive force in the third dimension Operates at room temperature in a laboratory setting Solidworks Model of Instron Machine Matthew Batten3

6. Project Description Construction of a device capable of laterally loading up to 200 N Work within a $2500 budget Fit within 10mmx12mm area under a magnetic field Provide feedback control Experimental Setup for MSMA Testing Joy Weber4

7. Design Concept Joy Weber5

8. Fabrication –This device was primarily fabricated using aluminum and 303/304 stainless steel. –Due to the high strength of this type of steel several design changes had to be made to facilitate the available tools. The bottom brackets were modified so that only one side had to be tapped instead of both. Plastic covers for the space where the actuator sits were added to reduce wear. During testing it was determined that the plastic covers allowed for deformation of the actuator assembly which was remedied by adding a hard stop at the end of the assembly that the actuator butts up against.
